![]() Due to the higher amount af coablt M42 is harder than M35. M35 has 5% cobalt include,d and M42 has 8% cobalt included. According to the Co mixture, cobalt drill bits are two types. Due to the hardness of the cable drill bits, it can be used to drill hardened metals such as welding seams. In ConclusionĬobalt drill bits are essential for both woodworking and metalworking. As mentioned in the table above, cobalt has a higher hardness than titanium. The hardness of an element or mineral has been identified as a measure of the relative resistance to scratching, and in this concept, the known hardness is derived from scratching against another material. Mohs Hardness Scale is an easy way to identify an element. The cobalt drill bits are a dull gold color and titanium bits can identify as HSS bits with brass or orange coloring. 1-5pcs HSS Cobalt Drill Bit for Drilling Stainless CR-NI & Hard Steel 1-5 MM TWU.

A high level of melting point helps to do the long-period drilling process. Therefore, it can be sharpened when it becomes blunt. And during the production process of cobalt drill bits from HSS drill bits, there has no outer surface painting process. On the ability and inability to sharpenĬobalt is an element between “ Mohs scale” numbers 7-8 and its means it is a harder metal.The durability of any drill bit depends on The durability of cobalt and titanium bits was discussed earlier in this article, but we will discuss them further here.
